Title: Centerless bar peeling device
Inventor: AOYANAGI TOORU
IPC: B23B5/12
Filed: 1984-03-19
Abstract: PURPOSE:To obtain cut processing without any undesirable step by delaying feeding speed by means of a resistance applied to the feeding device of an outgoing material drawing device and preventing generation of vibration by bringing the tip of a next-going bar-like material to be cut in close contact with the rear end of a preceding bar material. CONSTITUTION:A hydraulic motor 50 acts on an outgoing material drawing device 20 as a load resistance. As the result, drawing speed of a bar-like material to be cut 10 by the device 20 becomes lower than feeding speed for the material 10 by a roller device 12, and the bar material tip is pressed to the rear end of the next bar material in close contact with each other without shifting.

Filed: 1999-03-02
Abstract: PROBLEM TO BE SOLVED: To provide a magneto-optical recording medium, a method of recording and reproducing, and a device thereof capable of generating a reproducing clock accurately synchronized with recording marks on an information recording layer. SOLUTION: A magneto-optical recording medium 10 has a magnetic domain expanding and reproducing layer 3 and an information recording layer 5. Clock marks 8 are formed on the information recording layer 5, and a clock for reproduction can be generated based on this. To detect a clock mark 8, it is directly detected by emitting light of a wavelength λ2 (λ≠λ2) different from a wavelength λ1 for recording mark reproduction, or a reproduced signal is detected from the magnetic domain expansion reproducing layer 3 by transferring the clock mark 8 onto the magnetic domain expanding and reproducing layer 3 and enlarging the mark by applying a DC magnetic field.  Since the reproduction clock is accurately synchronized with the recording mark, it is suitable for a clock for reproduction of pulse-modulated reproduced light, reproduced magnetic field, etc., to be used at the time of reproducing the reproduction layer.
